US 2016/0239590 A1 · IDENTIFICATION AND PROTECTION METHOD OF ELECTRIC SHOCK ACCIDENTS

Abstract

The present invention discloses an identification and protection method of electric shock accidents, comprising the following steps: S100, building a multiport impedance network model of 3D human structure; S200, building a multiport distribution network model of human electric shock based on the impedance network model of the 3D human structure; S300, identifying the electric shock accident and taking actions for protection on the basis of the multiport distribution network model of human electric shock, and by use of wavelet and short-term energy methods. Based on the simulation results of the multiport distribution network model of human electric shock, the present invention could obtain the parametric features of zero sequence current from time/frequency domain, then identifies electric shock and start electric leakage protection by the combination of wavelet and short-term energy methods.
